Couldn't see RegionServer in Terminal-LINUX-HBASE

I installed hadoop and my HBase is running on top of it. All my deamons in hadoop is up and running. After i started my hbase i could see the HMaster running when i gave the JPS command.

I'm running my hadoop in Pseudo distributed mode . When i checked my localhost it shows regionserver is running.

But why couldn't i see the HRegionServer running in my Terminal in Linux?

It might be because hbase.cluster.distributed is not set or set to false in hbase-site.xml .
According to http://hbase.apache.org/book/config.files.html :

hbase.cluster.distributed :
The mode the cluster will be in. Possible values are false for standalone mode and true for distributed mode. If false, startup will run all HBase and ZooKeeper daemons together in the one JVM. Default: false

So if you set it to true you'll see the distinct master, region server and ZooKeeper processes. E.g: a pseudo-distributed Hadoop/HBase process list would look like this:

jps
3991 HMaster
4209 HRegionServer
3140 DataNode
3464 TaskTracker
3246 JobTracker
2942 NameNode
3924 HQuorumPeer
